MILK-CAN COVER.

SPECIFICATION forming part of Letters Patent No. 613,442, dated November 1, 1898.

Application filed September 4, 1897. Serial No. 0,595. (No model.)

To all whom it may concern.-

Be it known that I, OAssIUs OONGDON, a citizen of the United States, residing at West Clarksville, in the county of Allegany and State of New York, have invented a new and useful Milk-Gan Cover, of which the following is a specification.

My invention relates to milk-can covers, and particularly to a temporary protecting device for excluding animals, insects, smoke, dust, 850., while allowing free ventilation of the contents of the can while the latter is awaiting shipment to the factory or other point of destination. 7

The ordinary cover employed in connection with cans for shipping milk is closed, thereby allowing no ventilation for the contents, and if such a coveris employed in connection with a can of which the contents are still warm deterioration of the milk is liable to be the result. It is therefore desirable to delay the application of the closed or imperforate can-cover until the receptacles are about to be shipped, and it is necessary during this interval to protect the contents of the cans from depredations and pollution by cats, owls, chickens, flies, bugs, rain, snow,smoke, dust, cinders, &c. To accomplish this, I have devised a ventilating-cover for temporary use, the same being so constructed as to allow a circulation of air adapted to carry oif heated air and vapors and allow the natural cooling of the contents of the receptacle.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawing the figure represents a sectional view of a milk-can cover constructed in accordance with my invention applied in the operative position to the top of a receptacle.

The improved can-cover consists, essentially, of upper and lower domed deflectors 1 and 2, arranged to cover and conceal, respectively, subjacent annular vents 3 and 4, fitted with reticulated or interstitial guards 5 and 6, said guards being preferably arranged in horizontal positions, respectively,- above the planes of the lower pendent edges 1 and 2 of the deflectors. In the construction illus trated the upper and lower domed deflectors are of different diametrical measurements, the former being of less area than the latter, and said deflectors are respectively supported by upper and lower bands or collars 7 and8. The lower band or collar is adapted to fit the top of a milk-can or other receptacle 9, and the lower domed deflector is connected with said band or collar 8 bymeans of standards consisting of straps 10. The upper band or collar communicates with a central opening 11 in the lower deflector and supports the upper domed deflector by means of similar straps 12. These domed deflectors are respectively of greater diameter than the bands or collars by which they are supported, and the pendent rims l and 2,.for1ned by the downturned flanges at the peripheries of said domed deflectors, extend, respectively,

below the planes of the upper edges of said bands or collars by which the deflectors are respectively supported, while the interstitial guards, which fit in the "annular openings formed between the peripheries of the defiectors' and the said bands or collars, are arranged approximately in the .planes of the upper edges of said bands or collars, and hence above the planes of the lower edges of the pendent rims 1 and 2. The result of this relative construction and arrangement of parts is that an upward current of air enterin g the lower annular vent 4 passes upwardly, as indicated by the arrows in the drawing, and escapes through the upper outlet-vent 3, such upward current being induced by heated air and vapors rising from the con tents of the receptacle, whereas the deflectors, which inclose the interstitial guards above and at their sides, prevent flying objects from gaining access to the interior of the receptacle. Obviously the inclination and curvature of the exterior surfaces of the deflectors adapt the same to perform the functions of water-sheds, which carry falling objects beyond the annu lar vents and cause them to fall harmlessly at the sides of the receptacle. 7

Having described my invention, what I claim is 1 A ventilating receptacle-cover for the purpose described, having upper and lower axi-' ally alined bands or collars, the latter of which is adapted to fit the top of a receptacle,

in the latter, and horizontal interstitial guards fitted respectively in said annular vents above the planes of the peripheries of said deflectors, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
